[2020] Can´t login

Wrong steam build, restarted steam, nothing happened, verifying files, nothing happened, what I´m supposed to do to play?

Edit: There´s no option for beta or different builds on Steam.

Edit2: At 3:08 here it´s exactly the same, nothing has changed, no update on steam and wrong steam build in the game.

Edit3: What the hell happens? It still says wrong steam build...

Edit4: Now it´s updating, 519,4MB patch.

Edit5: Playing now, 3 others 1 AFK and me, we lost obviously, it´s wonky but it´s funny.

Edit6: Now stuck at matchmaking in the second try to play, restarted steam several times, it just get stuck there with cancel and quit greyed out everytime.
